You can also follow a Blender tutorial instead of translating a max tutorial to blender. The Blender community has produced a lot of good tutorials to learn hard surface modeling. Just make sure its a Blender 2.8+ tutorials.
I only found Delta transform on Root joint, but i cannot get any children joint prerotations in Blender. Am i missing something? Sorry, iam newbie in Blender.
EDIT: Stil not working in Maya, but blender did it with no problems at all. I´d still very much like help, so I can do it in Maya in the future, since I´d rather stick with Maya. (I have no prblem with blender, I am just a Maya lover ;P).
